Heartburn in late pregnancy

Hormonal changes can relax the muscle at the lower end of the food pipe, while the enlarging uterus increases pressure around the stomach. Burning may follow meals, become worse when bending or reclining, and leave a bitter or sour taste. A similar symptom can occur with acid reflux, and other digestive conditions can overlap. The symptom does not by itself identify one diagnosis.

Eat smaller portions and allow time for digestion before resting. Remain upright after meals, avoid tight waistbands, and keep a diary of triggers such as fatty meals, spicy foods, or drinks that worsen symptoms. Support your upper body during sleep without creating an unstable position. Discuss any acid reflux medication with your obstetric clinician or pharmacist before taking it.

Call emergency services for severe chest pressure, breathlessness, collapse, or pain moving into the arm, back, neck, or jaw. Seek prompt maternity advice for severe upper-abdominal pain, vomiting that prevents fluids, blood in vomit, black stools, difficulty swallowing, or heartburn with headache, visual disturbance, or sudden swelling. Assessment matters when the pattern changes or self-care is not enough.

Ask whether your symptoms match reflux, what treatment is compatible with your pregnancy, and which changes should prompt urgent review. Share your gestational stage, symptom timing, food and posture triggers, and all medicines or supplements.
